minimumslagernivå

Minimum slagernivå, or minimum stock level, is the lowest amount of an item that a company should keep in inventory to meet expected demand during the supplier lead time and to avoid a stockout. It is a core parameter in inventory management and helps balance service level against holding costs.

How it is determined depends on lead time, average usage, and variability in demand. A common calculation is minimum stock level = expected demand during lead time + safety stock. If demand is relatively constant, expected demand during lead time equals the average usage per period multiplied by the lead time. Safety stock covers uncertainty in demand and supply and is often estimated as safety stock = z × σLT, where σLT is the standard deviation of demand during lead time and z corresponds to the desired service level.

The minimum level is used in various inventory policies, such as min–max systems or kanban-like controls, to guard against stockouts and to trigger replenishment events. It is related to, but distinct from, the reorder point. The reorder point generally represents the stock level at which a replenishment order should be placed, while the minimum level serves as a floor that helps ensure stock does not fall below an acceptable level during lead time.

Practical considerations in setting minimum slagernivå include seasonality, demand variability, supplier reliability, product value, and target service level. Regular review and adjustment are common as demand patterns and supply conditions change. The concept supports risk management by maintaining sufficient buffer stock while controlling carrying costs.
